ErSb5

ErSb5 is an intermetallic ceramic compound composed of erbium and antimony, belonging to the rare-earth pnictide family of materials. This is a specialized research compound rather than a widely commercialized engineering ceramic, studied primarily for its electronic and thermal properties in the context of rare-earth intermetallics. The material is of interest to researchers investigating high-temperature semiconductors, thermoelectric applications, and fundamental solid-state physics, where the specific electronic structure of rare-earth-antimony phases offers potential advantages in niche thermal or electronic conversion scenarios.
